Specification of Letters Patent.

Application filed December 22,1905. Serial No. 293.031.

To @ZZ whom it may concern:

Be it known that I, CLARENCE'L. TAYLOR, of Alliance, in the county of Stark and State of Ohio7 have invented certain new and useful Improvements in Ingot-Charging Cranes;

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in ingot charging cranes, and it consists in the parts and combinations of parts as will be more fully described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in longitudinal vertical section of my improved apparatus, Fig. 2 is a view in plan, the ingot charging bar being shown in section. Fig. 3 is a view in cross section showing the gearing for,rotating the charging bar, and Fig. 4 is an end elevation of the charging bar and the cross head to which it is connected showing the gearing for actuating the tongs opening and closing mechanism.

1 represents a truck mounted on wheels 2 which latter travel on a trackway 3 running lengthwise the mill. Mounted on the -truck is the circular turn table 4, the latter being carried on the spherical anti-friction bearings 5 mounted in a grooved trackway 6, the turn table 4 being also grooved to receive the spherical bearings. This turntable, is as before stated circular in form, with an open center, and is provided with a depending circular sleeve 7 having an outwardly projecting shoulder 8 which latter rests under the annular shoulder 9 formed on the circular member of truck 1, anti-fric tion spherical bearings 10 being introduced between the two shoulders and resting in grooves in said shoulders. The depending sleeve with its shoulder resting under a shoulder on the truck absolutely prevents any tipping of the turn table on the truck, while the spherical bearings interposed between said parts, reduce the friction to a minimum.

Secured to the turn table are upright frames or supports 11 carrying the parallel girders 12, which latter are provided on their upper surfaces with track rails 13 on which the trolley 14 travels lengthwise the girders.

The truck 1 is propelled by motor 15 coupled up by gearing 'with one pair of track 'wheels 2 (see Fig. 2); the turn-table 4 is rotated by motor 16 and suitable gearing carried by truck 1, one pinion 17 of the gearing meshing with the rack 17 a on the 'turn table, while the trolley is moved back and forth on the girders 12 by the motor 1S, and gearing connecting the motor and one pair of track wheels supporting the trolley 14.

I/Vith the construction thus far described, it will be seen that the entire apparatus can travel on the floor rails 3 lengthwise the mill 5 the frames 11, girders 12, and trolley 14 can be turned by the rotation of the turn table 4, and the trolley moved back and forth on the girders 12, thus bringing the tongs carried by the charging bar, to any position within the limits of its movements, on both sides and at the ends of tracks 3.

The several motors already referred to, and those which rotate and tilt the charging bar and open the tongs to be hereinafter referred to, are all under the control of the operator located in cage 19 depending from the trolley 14, the operating levers 2O of the several controllers 21 projecting down into the cage within convenient reach ofthe operator. Depending from the trolley 14 near the front end of the latter is the yoke 22 to which the charging bar carrying frame 22a is pivoted as at 23, the latter being in a plane above the charging bar.

24 are braces which are secured at their upper ends to the trolley in rear of the yoke 22 and. project downwardly and forwardly and are secured at their lower ends to the yoke at a point adjacent to the pivot 23. This yoke 22 and braces form a solid substantial and unyielding bearing on which the charging bar carrying frame 22arocks. This frame 22a is as shown in FiO. 1, mounted on the pivot 23, and is pivotazlly connected at its rear end to the rods 25 which latter are connected at their upper ends to the bar 26 connecting the segmental gears 27. These gears 27 are secured to shaft 28 and are in mesh with pinions 29 on shaft 30. This shaft carries at its end a large toothed wheel 31, which meshes with pinion 32 on shaft This shaft also carries a pinion 34 which meshes with the smaller pinion 35 on shaft of the motor 36. By means of this motor and gearing, the segments 27 may be turned to IOO elevate or lower the rear end of the charging bar carrying 'frame 22 and thus lower and elevate the tongs at the outer end et the charging bar.

The charging bar 37 is journaled at its ends in the charging bar frame 22, so as to rotate therein, and is provided with a circumferential worm 39a engaged by a worm shaft 39" driven by the motor 39. By rotating the armature of the motor 39 the charging bar, may, through the gearing shown, be turned so as to present either side of the tongs up, or to turn any object held by the tongs.

The tongs 40, are opened and closed by the longitudinal movement of the rod 41 extending lengthwise through the center of the charging bar. The rear end et this rod is screw threaded, and is engaged. by a nut 42 carrying a pinion 43. This pinion is actuated by gearing shown diagrammatically in Fig. 4, from the motor 44, and when rotated, moves the rod41 longitudinally and opens and closes the tongs, the direction of movement ofthe tongs members being dependent on the direction of rotation of the nut 42.

The rod 4]V is shown in two sections swiveled together, as shown at 45, so as to permit the outer end thereof, which actuates the tongs, to turn with the tongs without rotating the screw threaded rear section.

llVith the apparatus constructed as described, with the motor 39 tor rotating the charging bar mounted on the bar carrying frame 22%, the bar can be turned or rotated in its bearing, while its outer or tongs end is being raised or lowered as explained, and by mounting the tongs opening and closing moter on the trame 22a the tongs can be opened and closed simultaneously with the rotary and tilting movements of the charging bar.

lt is evident that many slight changes might be made in the relative arrangement of parts herein shown and described without departing from the spirit and scope ol my invention hence l would have it understood that l do not wish to conline myself to the exact construction of parts shown and described7 but,

Having fully described my invention what l claim as new and desire to secure by Letters-Patent, is :n

l. In an ingot charging apparatus, the combination with a trolley, a support depending from same and a charging bar carrying iframe pivotally secured te said depending support, et a charging bar iournaled in said trame, tongs carried by said bar motor and gearing carried by the carrying frame for rotating the charging bar, a motor and gearing carried by the carrying 'frame Yfor opening and closing the tongs, means carried by the trolley and engaging the carrying frame for rocking the latter and an operators cage indeesaaa pendent of the carrying traine and suspended from the trolley.
